INTEL Xeon 6558Q 3.20GHz CPU
The Intel Xeon Gold 6558Q is a 32-core, 64-thread server processor from the Xeon Scalable family with a 3.20 GHz base clock and 4.20 GHz max turbo frequency, suited to virtualization hosts, general-purpose compute nodes, and storage or database workloads that benefit from high core counts. It installs in LGA 4189 sockets, so buyers must confirm motherboard and BIOS platform compatibility before ordering, and supports 2-socket configurations for scalable deployments. This unit is a practical option for integrators and data centers refreshing existing LGA 4189 platforms.

Good to know
- Compatibility: Requires an LGA 4189 socket motherboard (e.g., Whitley/Cedar Island generation platforms); confirm BIOS revision and memory DIMM type (DDR4 vs DDR5) with your server vendor, as supported memory depends on the platform.
- Family positioning: Within the Xeon Scalable Gold tier, this SKU pairs a high 32-core count with a strong 4.20 GHz turbo, making it versatile for mixed virtualization and compute workloads where lower-clocked high-core parts or high-clocked low-core parts fall short.
- Buying tip: Since the processor supports up to 2-socket configurations and 64 PCIe 4.0 lanes per CPU, evaluate your expansion needs (NVMe backplanes, NICs, accelerators) before choosing between single- and dual-socket builds, and validate bulk pricing and tray/boxed packaging when sourcing volume.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
